She also made more than $2,000 on the purifiers that were delivered, although it violates district policy for a principal to profit from sales to her school.Moreover, Chaniott was paid more than $6,800 for selling air purifiers at a previous school. It was not determined how many of those were delivered.Chaniott also violated district policy by hiring her son and another person to paint the school without putting the project out to bid.
